Fig. 4


Parallaxes predicted from Eq. (1) at the mKs magnitudes of the RC stars and those of TGAS. The full red line shows the 1:1 relation. The black lines give the linear fit between the parallaxes with the associated 1-σ uncertainty given by the blue shaded regions. The green dashed line shows the predicted off-set of −0.39 mas from Stassun & Torres (2016), adopting an ecliptic latitude of β = 55° of the Kepler field-of-view. The marker colors indicate the mKs magnitudes of the stars. The correction of Eq. (2) is given by the difference between the 1:1 relation and the linear fit.
